Processed the LiDAR lines. Couple of problems:
Line 1 has a large blank down the middle, looks like its a range gate issue
Line 4 has only processed partly, about one third, not sure why as ASLPP does not show any errors
Line 5 does not process at all, ALSPP crashes when I load it in

Processed the IPAS honeywell nav data for 260b - which was fine. After checking further looks like a corrupt file in ipas_honeywell/raw was causing the problem. It is the same on thelma so must have been a problem when downloading from the aircraft. Replaced corrupt nav file with the one from day 260 b.
